Staple and nail extractor



May 27, 1930. F. N. YOUNG STAPLE AND NAIL EXTRACTOR Filed Oct. 2, 1926Patented May 27, 193i) creator PATEN T GFFEQE FREDRICK Iii. YOUNG, OFCLAREMONT, NEW HAMPSHIRE STAPLE AND NAIL EXTRACTOR Application filedOctober 2, 1926.

The present invention pertains to a novel staple and nail extractorconstructed in a simple manner and adapted to accomplish its expectedfunctions as effectively as possible.

The device comprises essentially a housing in which are supported afixed jaw and a movable aw. The movable aw is formed with a cam face orsimilar arrangement adapted to be engaged by a handle which is alsopivoted in the housing. The aws when opened are placed at opposite sidesof the nail 0r staple, and the handle is then swung on its pivotso thatthe movable jaw closes against the fixed jaw whereby the nailor stapleis grasped between the two jaws. Continued pressure on the handle causesthe entiredevice to swing about a heel or a bearing piece carriedthereby whereupon the nail or staple .s extracted.

The invention comprises further a hammer taple or nail head which cannototherwise be reached.

The invention is fully disclosed in the following description and in theaccompanying drawings in which:

Reference to these views will now be made by use of like characterswhich are employed. to designate corresponding parts throughout.

The staple extractor shown in Figures 1 to inclusive comprises a hollowhousing lhavin a bearing piece or heel 2 projecting from the forwardside thereof. Within the housing, near the upper wall thereof is secureda stationary jaw 3 and a pivoted jaw4. The

aws are opposed to one another and held to the top of the housing byscrews 5, the stationary jaw being further maintained by a pin 6 whichprevents turning. The shank of the swinging jaw 4 is formed with arecess adapted to provide an arcuate cam 7 as clearly shown in Figures 2and 3. Through the rear wall of the housing is passed a handle 8 whichis fastened therein by a pivot pin 9 on which it is adapted to turn. Theinner end of the handle is formed with an angular upwardly directedprojection 10 formed with a bevelied head designed to engage the camformed on the swinging jaw 42 and forcibly swing the jaw to closedstaple engaging position; The projection 10 is accommodated in a notch11 cut in the upper wall of the housing. The handle 8 is maintained in acentral position with respect to the pin 9 by means of spacing rings 12surrounding the pin at both sides of the handle.

The handle 8 is surrounded by a heel 13 which is used as a hammer fordriving the points of the jaws 3 and at into the wood when the stapleis'embedded therein too far to be reached otherwise. In such a case theheel 13 is drawnoutwardly with respect to the handle 8 and then drivenforcibly against the handle after the claws have been placed at oppositesides of the staple. The end of the handle is cushioned as at 14: and isalso equippedwith 15 held by a pin 16 passed through both the handle andthe ring. The forward end of the'heel has a collar 17 threaded thereinand adapted to slide loosely on the handle. This collar in conjunctionwith the ring prevents the heel from being pulled ofl the handle.

The use of the device is illustrated more clearly in Figure at in whichis illustrated a post 18 having a staple 19 driven therein. The clawsare placed at opposite sides of the staple in such a manner that thehandle 8 assumes substantially a horizontal position. The points of thejaws 3 and 4 are driven into the wood if necessary and the handle 8 isthen lowered whereupon the point 10 riding against the cam face 7 causesthe movable jaw 4 to swing towards the fixed jaw 3 whereby the staple isgrasped between the two jaws. The downward pressure of the handle 8 iscontinued whereby the entire device is caused to swing about the heel 2as a pivot so that the staple is withdrawn.

The same construction as modified rm a nail puller is illustrated inFigures 6 to 9 inclusive. The housing for this device comprises a pairof plates and 21 secured to gether by screws 22 and having internalflanges 23 so that an interior cavity is formed for accommodating theworking parts. A fixed jaw 24 and a swinging jaw 25 project through theforward end of this housing and are maintained in position by bolts 26which further serve to support a bearing piece 27. The fixed aw 24 isfurther held by a pin 28 passed through the plates 20 and 21 in order toprevent turning. Theshank 29 of the swinging jaw 25 has in its outeredge a notch 30 which receives one end of a flat spring 31 secured toone of the flanges 23. This spring tends to move the inner end of thejaw 25 towards the fixed jaw 24 and thereby to separate the points ofthe tWo jaws. The inner edge of the swinging jaw is formed with a recess32 for receiving a lug 34 on the inner end of a handle 33 pivotallysupported between the plates 20 and 21 by a pin 35. The

operation of this device is substantially similiar to that previouslydescribed except that in this instance the handle swings in the plane ofthe jaw rather than in a plane perpendicular thereto.

l/Vhile a specific embodiment of the invention has been illustrated anddescribed, it is to be understood that various alterations in thedetails of construction may be made without departing from the spiritofthe invention 3 as indicated by the appended claim.

Having thus fully described the invention, what I claim as new anddesire to protect by Letters Patent is An extractor comprising ahousing, a fixed jaw secured in the housing and having its outerengaging end projecting longitudinally from one end of the housing, apivoted jaw mounted in opposed position to the fixed jaw and adapted toadjustably co-act therewith,

and a handle arrangedrearwardly of and contiguously with said movablejaw and extending longitudinally from the opposite end of the housing,said handle being pivoted to said housing for swinging movement in aplane at right angles to the swinging movement of.

hand.
